The handle is provided with a slot l2 extending transversely and longitudinally thereof medially of the thickness of the handle and opening to one end of the handle, this slot terminating at its inner end at a location spaced from the other end of the handle.

The blade H is of elongated, substantially rectangular shape with straight and substantially parallel side edges l3 and I4 which are bevelled "and, sharpened throughout their length to proits longitudinal" edges sharpened .dinally. extending Icliosed .slot w p site sides or the-midi eneth locational :2 uide cutting :edgesaextendi'ng onealong -:each;side ofiitheiblade.

The blade can then be turned about the screw 2| until the portion thereof having the dulled cutting edges is disposed in the handle slot and the portion previously disposed in the slot extends longitudinally from the handle. The blade is then pushed back into the handle until the abutment pin I8 is received in the notch in the end oi "when hotness-heeating esgesen'the portmn.

the blade now disposed in the handle slot and the clamp screw 2| is tightened to secure the blade firmly in operative position in the handle with undulled portions of its cutting edges extending longitudinally from the end of the handle to which the slot l2 opens.

When it is desired to replace an old blade with a new blade, the clamp screw 2| is removed entirely from the handle, the old blade pulled out of the handle slot 12 and one end portion of a new blade inserted in the handle slot until the abutment pin 18 is engaged in the notch in the end of the new blade disposed within the handle slot and the clamp screw 2| is then replaced and tightened to firmly secure the new blade in the handle.

The handle can be formed of any suitable material, such as wood, synthetic resin plastic, hard rubber or metal, and the blade is formed of a suitable material, such as steel, on which a cutting edge can be provided. The blade is of simplified form and a plurality of blades can be economically manufactured from a strip of steel, the edges of which are bevelled and sharpened and which is subsequently cut into suitable lengths to provide the blades H, the notches in the ends of the blades being provided when the blades are cut from the strip. This provides an economical manner or manufacturing the blades so that the blades are of nominal cost and can be discarded and replaced by new blades when their cutting edges have been dulled and there will be no necessity for resharpening the cutting edges of a blade.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is, therefore, ,to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.

What is claimed is:

1. A hand knife comprising a handle having atransversely and longitudinally extending slot medially of the thickness thereof and opening to one end of the handle and terminating at a location spaced from the other end of said handle, an elongated blade having its longitudinal edges sharpened and having a notch in each end there of and a longitudinally extending slot extending to opposite sides of its midlength location, substantially one half of the length of. said blade being received in the slot in said handle, abutment means comprising a pin adjacent said other end of said handle extending transversely through the slot in said handle and engaged in the notch in the end of the blade disposed within said handle slot, and means extending through the slot in said handle and the slot in said blade clamping said blade in position in said handle.

2. A hand knife comprising an elongated handle having a transversely and longitudinally extending slot disposed medially of the thickness thereof and opening to one end of the handle and terminating at a location spaced from the other end of said handle, a blade of elongated substantially rectangular shape having it longitudinal edges sharpened and having a notch in each end thereof and a longitudinally extending slot extending to opposite sides of its midlength location medially of the width thereof, the slot in said handle having a length somewhat greater than one half of the length of said blade and substantially one longitudinal half of said blade being received in the slot in said handle, abutment means comprising a pin adjacent said other end of said handle extending transversely through the slot in said handle and engaged in the notch in the end of the blade disposed within said handle slot, and a clamping screw extending through the slot in said handle near the end of said handle to which the handle slot opens and through the slot in said blade and clamping the portions of said handle at the respectively opposite sides of said blade against said blade to hold the blade in position in the handle.

3. A hand knife comprising a handle and an elongated blade having its longitudinal edges sharpened throughout their length, a transversely and longitudinally extending slot in said handle medially the thickness thereof opening to one end of the handle and terminating at a location spaced from the other end of the handle, anabutment pin extending transversely through said handle and said slot adjacent the other end of the handle, V-shaped notches at either end of said blade, a longitudinally extending slot closed at both ends in said blade medially its width and extending to opposite sides of the midlength location of said blade, approximately onehalf of the length of said blade being adapted to be received in the slot in said handle and said notch in the blade end engaging said abutment pin, and clamping means comprising an internally threaded sleeve and a clamp screw threadingly received therein carried by said handle adjacent the end of said handle to which the handle slot opens and pressing the sides of said handle at opposite sides of said blade against the blade to secure the blade firmly in the handle.
